Embodiment 1
[0031] as attached Figure 1~4 As shown, a method for arranging a grain ventilation duct provided by an embodiment of the present invention, the arranging method includes the following steps:
[0032] S101, laying out a "well"-shaped ventilation duct with the grain bag 1 filled with the grain 2;
[0033] S102, then cover the grain bag 1 filled with the grain 2 on the laid "well"-shaped air duct to form a closed air duct with openings around;
[0034] S103, finally ventilating and cooling the closed ventilation duct.
[0035] Specifically, when laying the "well"-shaped ventilation duct, that is, the first layer of grain bags, it is laid at intervals along the length and width of the area to be laid. efficiency to decide. Generally speaking, the distance between two adjacent ventilation ducts is 4-5m, which not only meets the requirements of manual passage, but also meets the requirements of mechanical passage, and the ventilation efficiency is good. When arranging in a fami...
Embodiment 2
[0041] as attached Figure 2-8 As shown, an arrangement method of a grain ventilation duct suitable for the ventilation treatment of grain in a granary provided by an embodiment of the present invention, the arrangement method includes the following steps:
[0042] S201, first put grain 2 into packaging bags of the same size, and after sealing, obtain a large number of grain bags 1 filled with grain 2; ~50kg grain 2;
[0043] S202, then place the grain bags 1 in the one-story granary, and lay 2-4 layers at every 4-5m from the length and width of the granary floor to form a "well"-shaped ventilation duct, such as Figure 5 with 6 shown;
[0044] S203, then vertically lay the grain bag 1 on the top of the "well"-shaped ventilation duct for 1-3 layers, add a cover and support it, and finally form a closed ventilation duct with a height of 0.8-1.5m around the opening, such as Figure 7 shown;
[0045] S204, then maintain a distance of 1-2m between the airtight ventilation duc...

Abstract
The invention is applicable to the technical field of grain ventilation, and provides an arrangement method of a grain ventilation air duct. The method includes the steps that the ventilation air duct shaped like a Chinese character 'jing' is paved by using grain bags filled with grains; the grain bags filled with the grains cover on the paved ventilation air duct shaped like the Chinese character 'jing' to form a closed ventilation air duct with openings in the periphery; and the closed ventilating duct is ventilated and cooled. According to the arrangement method of the grain ventilation air duct, a traditional measure that a mechanical device is adopted for arranging the ventilation air duct is changed, and the grain bags filled with the grains are directly adopted for building the ventilation air duct, so that the built ventilation air duct is communicated all around, and circulation of air flow is facilitated. Compared with the prior art, the arrangement method has the beneficial effects that the ventilation efficiency is high, and the grain storage loss is small; the ventilation air duct is formed by building the grain bags filled with the grains, so that a large machine can transfer the grains conveniently; and the method is in low investment cost, convenient in operation, time-saving and labor-saving in arrangement, and suitable for popularization in novel agricultural operation subjects such as large grain planting households, family farms, professional collaborats and grain collection, storage and processing enterprises, and the like.
Description
technical field [0001] The invention belongs to the technical field of grain ventilation, and in particular relates to a method for arranging grain ventilation ducts. Background technique [0002] Post-harvest food losses are a global problem. As a major grain producing country, China suffers from serious grain loss after harvest, and grain loss during storage accounts for a relatively high proportion of post-harvest loss. During the storage of grain, due to respiration, heat is produced and part of the water is evaporated. If the temperature is not cooled and dehumidified in time, the mold and deterioration of the grain will be accelerated. At present, the commonly used measures are mechanical ventilation and cooling grain storage technology. The ventilation system is mainly composed of ventilators and ventilation ducts arranged on the ground of the granary. The ventilators are used to make the external low-temperature air pass through the grain piles through the ventilati...
